Recently I’ve got more time to operate radio, so I’ve been working on my DXCC totals. Its becoming very, very addictive. For various reasons, my Antenna isn’t exactly a work of art. It is a 7m long piece of wire taped to a fibre-glass fishing pole, tuned against ground. I’m predominantly operating in “search-and-pounce” mode using morse code, where I continuously tuning up and down, looking for stations (rather than sitting on a frequency, and putting out endless CQ calls). While it’s not very efficient, it’s great fun, and I’m really enjoying it.
So, where do I stand? Well at the moment, I’ve 87 different DXCC entities worked, with 55 confirmed. Visualising this using Xplanet, it looks like:
Green are DXCC entities that I’ve already worked and confirmed. Yellow are ones worked but not confirmed, Red are ones that I’ve not worked yet. If I can keep my current level of activity, HF band conditions keep improving, and I “work” more stations that use Logbook of the World, rather than depending on QSL cards (my own below), I should achieve 100 countries confirmed by the summer. In theory 😉
Well, not quite, but you will understand when you read this. Bertrand, F5PL, recorded the tone of the Radio Carrier from Mars Express as it approached Phobos. Great work from an “Amateur”.
Great videos on how one can capture data that is unintentionally transmitted by interconnecting cables.
The receiver used is a Software Defined Radio, specifically the Ettus Research USRP. The software is based on the GNU Radio suite.
…is available here. And I feel old looking at it.
This is a very funny post from Jeff, KE9V.
Dmetry and Olaf walked into a dimly lit tavern and selected a booth far in the back where they could not be easily overhead. Dmetry was a hulking 300 lbs man who had muscled his way into the lower echelons of leadership in the Russian mafia but he was most interested in disappearing a very wealthy man as soon as possible.
It goes on..
“This application includes a Trojan horse; it will offload itself from the primary application upon installation, and play hide and seek with any anti-virus measures that may have been installed” Olaf said as a perverted grin spread across his face. “Then when we are ready, we will have at our disposal 100,000 networked computers that will do our bidding whenever the signal is given”.
Dmetry wasn’t easily convinced. “But why, why should these people be willing to install this botnet?”
Olaf replied, “They have no idea what they are doing. Urmil has written an application for radio amateurs, maybe you’ve heard of these radio ‘hams’, no? They love to play with their computers and their radios but they know little about the technology behind it all. This new application will be software that permits their computers to communicate via HF radio, they are crazy for free software and shiny new baubles to play with.”
“We will tell them that this software is for a new mode of communication and it will spread like wildfire in their community. They will never be the wiser…”
So funny, but it isn’t all that big a leap to see it actually happening. Very funny, thanks Jeff.
(Of course I use fldigi, build it from source, and keep an eye on what stuff is actually leaving my machine as much as possible.)
Recently, Hessu, OH7LZB, began the process of migrating his service to IPv6. While he isn’t finished (AAAA still to be added) ipv6.aprs.fi is up and running and usable today.
ARVN has just released a set of DVDs covering the presentations at the TAPR DCC. I was at the DCC last September and purchased some DVDs from Gary and I found them good viewing quality, and, being the DCC, excellent content 🙂
Bill Meara on whether black holes exist in workshops? Followed by a (very funny) explanation of what various tools are used for.
The Feb. 27 magnitude 8.8 earthquake in Chile may have shortened the length of each Earth day.
JPL research scientist Richard Gross computed how Earth’s rotation should have changed as a result of the Feb. 27 quake. Using a complex model, he and fellow scientists came up with a preliminary calculation that the quake should have shortened the length of an Earth day by about 1.26 microseconds (a microsecond is one millionth of a second). More.
Also, as a result of the earthquake, there is a lot of activity on Amateur Radio frequencies of 7050, 7060, 7088, 7095. As there is a contest next weekend, please listen carefully before using these frequencies. More.
